Embodiment Construction
[0031] The present invention will be further explained below in conjunction with specific embodiments, but the present invention is not limited thereto.
[0032] The invention provides a flame identification method based on infrared multi-feature joint technology, comprising the following steps:
[0033] S1: Use the infrared camera to obtain the infrared image and temperature information of the monitoring area;
[0034] S2: Find the suspected flame area S, and according to the lowest temperature T of the suspected flame area S min Perform high-pass filtering on the infrared image to filter out the low-temperature background, and further obtain the suspected flame area S 0 , where the suspected flame area S in the infrared image has a temperature greater than the temperature threshold T 0 Or the temperature increases to the temperature sudden change coefficient K 0 Times and K 0 A collection of pixel points more than twice;
[0035] where the temperature threshold T 0 and...
